Another issue that you did not mention is do you want detail in the background cloth? If not you have too much illumination of the background whic should be further away from the subject. Also will you be scanning the negatives and printing digitally? If so there are the scanner, scanner software, monitor, printer and paper that any or all can make a difference.

The OP asks how to correct the images he has. My advice stands for those images. However, as everyone else has pointed out, and correctly, the film is daylight balanced and was shot with tungsten illumination.

This is, when you get down to it, uncorrectable. See the excellent illustration of this in the book by Ctein, "Post Exposure".

I meant to say how to correct this type of shot in the future, not to correct these photos.
